I really do not like those Polyvaricon tuning capacitors I don't think the tuning range is sufficient to cover the whole AM broadcast band. So then you have to fiddle with the ferrite slug of the coil.
I might remove the Polyvaricon varable capacitor & use one from a scrap radio. At least I could add a proper reduction drive & get the spindles & pulleys from a scrap radio.
